Slide 2

Widdowson· Studied a group of children who suffered from deprivation dwarfism· A change in diet didn't improve them but a change in supervisor did. The old supervisor was harsh and the new on was kind· This shows that good emotional care rather than good physical care was the cause of their improvementsEvaluation· High ecological validity as it used a real life situation· Low population validity as it only involved one orphanage, can't generalise results as different orphanages may use care that effects children differently…read more

Slide 3

Widdowson· High internal validity as only one variable changed which was the type of care (IV), so we can be sure that the results are due to this and not any other confounding variable…read more
